Notice to Shareholders

[Guideline for Implementing the Shareholder Return Plan that Prioritizes Enhancing Shareholder Value]

 

Recently, the uncertainty in both domestic and international political and economic conditions, along with the resumption of short-selling, has led to continued instability in the stock market. In response, Celltrion once again emphasizes its commitment to making company-wide efforts aimed at enhancing shareholder value and increasing corporate value.

 

Continuing to implement the shareholder return plan that prioritizes enhancing shareholder value.

 

  • Celltrion will continue to overcome challenging internal and external conditions while steadfastly implementing the 'Value-Up Program’, a corporate value enhancement plan promised to our shareholders. Through this, we will proceed with a shareholder return plan that prioritizes the enhancement of shareholder value without wavering. We aim to achieve three key goals: ▲ An annual growth rate of over 30% until 2027, ▲ A return on equity (ROE) of over 7% by 2027 through expanded profitability, and ▲ An average shareholder return rate of 40%
  • Celltrion will continue its shareholder return initiatives through stock buybacks, cancellations, and cash dividends. Just three days after announcing the Value-Up Program, we decided to acquire approximately 50 billion KRW worth of treasury stock and swiftly completed the purchase. Today (April 2), we have decided to cancel all of the treasury stock we recently acquired. We will continue to cancel all additional treasury stock purchased moving forward.
  • Celltrion will continue to enhance shareholder value. In response to the uncertain domestic and international market conditions, if the company's value remains undervalued, we are committed to proactively protecting shareholders' interests through additional shareholder-friendly policies, including active buybacks, cancellations of treasury stock, and increasing dividends.

 

Uncertain market conditions continue both domestically and internationally. As a result, there are significant concerns that the domestic stock market may continue to experience instability. In response, Celltrion will continuously monitor stock market changes and proactively respond to market fluctuations. We promise to continue making every effort to sustain corporate value that prioritizes shareholder value.

 

Thank you.

STEQEYMA® (ustekinumab-stba), a biosimilar to STELARA® (ustekinumab), now available in the United States

  STEQEYMA®, one of the first-wave biosimilars to STELARA®, is now available in the U.S. Approved for the same indications as the reference product, STEQEYMA will be priced with a wholesale acquisition cost (WAC) list price at an 85% discount to the current WAC list price of STELARA to help improve patient access to high-quality biologic treatments[1] With the launch of STEQEYMA, Celltrion expands its immunology portfolio beyond tumor necrosis factor (TNF)-alpha inhibitors, to include interleukin (IL)-12 and IL-23 inhibitors, broadening treatment options for multiple immune-mediated diseases Celltrion has nine biosimilars and five immunology biologics granted marketing authorization in the U.S. JERSEY CITY, N.J., March 12, 2025 - Celltrion today announced the U.S. launch of STEQEYMA® (ustekinumab-stba), a biosimilar to STELARA® (ustekinumab), following approval by the U.S. Food and Drug Administration (FDA) in December 2024. STEQEYMA is approved for the same indications as STELARA, providing consistency in treatment for patients and healthcare providers.[1] STEQEYMA is indicated for the treatment of plaque psoriasis (PsO) and psoriatic arthritis (PsA) in adult and pediatric patients, as well as Crohn's disease (CD) and ulcerative colitis (UC) in adult patients. It is available in both subcutaneous injection and intravenous infusion.[1] "Chronic inflammatory diseases such as plaque psoriasis and psoriatic arthritis place significant burden on patients," said Mark G. Lebwohl*, MD, Icahn School of Medicine at Mount Sinai, New York. "Biosimilars increase access to essential therapies, while maintaining the same high standards as the reference product. The availability of STEQEYMA provides patients and healthcare providers a cost-effective alternative to manage chronic inflammatory diseases." STEQEYMA will be priced with a WAC list price at an 85% discount to the current WAC list price of STELARA to help improve patient access to high-quality biologic treatments. The FDA approval of STEQEYMA was based on the totality of evidence, including the results from a Phase III study in adults with moderate to severe plaque psoriasis, in which the primary endpoint was the rate of change in the Psoriasis Area and Severity Index (PASI) for skin symptoms. The clinical results demonstrated that STEQEYMA and its reference product, ustekinumab, are highly similar, and have no clinically meaningful differences in terms of safety and efficacy. [2],[3] "The introduction of STEQEYMA in the U.S., as one of the first-wave biosimilars to STELARA, marks an important step in our ongoing efforts to expand patient access to high-quality biologic treatments," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA.

U.S. FDA approves Celltrion's OMLYCLO® (omalizumab-igec) as the first and only biosimilar with interchangeability designation referencing XOLAIR®

OMLYCLO® (omalizumab-igec) is the first and only omalizumab biosimilar approved by the FDARegulatory approval for interchangeability was supported by positive phase III data demonstrating comparable efficacy and safety profile with the reference product XOLAIR® (omalizumab)[1]The availability of the first omalizumab biosimilar will help increase access and potentially lower the healthcare cost for people with asthma and allergic diseases JERSEY CITY, N.J., March 9, 2025 /PRNewswire/ -- Celltrion today announced the U.S. Food and Drug Administration (FDA) approved OMLYCLO® (omalizumab-igec) as the first and only biosimilar designated as interchangeable with XOLAIR® (omalizumab) for the treatment of moderate to severe persistent asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), Immunoglobulin E (IgE)-mediated food allergy, and chronic spontaneous urticaria (CSU).[2]  "We are proud to achieve the approval of the first biosimilar to omalizumab in the U.S., which will help broaden access to this important medicine for patients with allergic and respiratory conditions, as well as for physicians, payers and providers," said Hetal Patel, Vice President of Medical Affairs at Celltrion USA. "The interchangeability designation of OMLYCLO reinforces confidence among physicians and patients that there is no decrease in effectiveness or increase in safety risk associated with switching between OMLYCLO and the reference product." The FDA approval and designation of interchangeability are based on comprehensive clinical evidence, including results from a global Phase III clinical trial involving 619 adult patients with CSU up to Week 40. Patients were randomized to receive 300 mg or 150 mg of OMLYCLO or reference product every 4 weeks. From Week 12, patients who received OMLYCLO were continued on OMLYCLO, and patients who received 300mg of the reference product were re-randomized in a 1:1 ratio to switch to OMLYCLO or to continue reference product. From Week 24, patients were followed up until Week 40 without dosing. The result demonstrated the comparable efficacy and safety of OMLYCLO to reference product during both treatment and off-dose periods.[1] An interchangeable biosimilar is a biosimilar that meets additional requirements outlined by the law that allows for the FDA to approve biosimilar and interchangeable biosimilar medications.[3] "The approval of OMLYCLO could have a meaningful impact for the medical community and patients, offering a high quality and affordable treatment option, while reducing the burden of healthcare costs," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. "With our integrated development, manufacturing, and commercialization platform, Celltrion remains committed to alleviating treatment costs and delivering life-changing medicines to support patients with allergic conditions in the U.S." About OMLYCLO® (omalizumab-igec)  OMLYCLO® (omalizumab-igec) is the first U.S. Food and Drug Administration (FDA)-approved anti-IgE antibody biosimilar referencing XOLAIR® (omalizumab). OMLYCLO 75 mg/0.5 mL and 150 mg/mL solution in a single-dose prefilled syringe is approved as interchangeable with reference product for all indications based on comprehensive data and clinical evidence confirming the therapeutic equivalence to XOLAIR.[1],[2] OMLYCLO was also approved by the European Commission (EC) in May 2024. INDICATIONOMLYCLO® (omalizumab-igec) injection, is an anti-IgE antibody indicated for: Moderate to severe persistent asthma in adults and pediatric patients ≥6 years of age with a positive skin test or in vitro reactivity to a perennial aeroallergen and symptoms that are inadequately controlled with inhaled corticosteroidsChronic rhinosinusitis with nasal polyps (CRSwNP) in adult patients ≥18 years of age with inadequate response to nasal corticosteroids, as add-on maintenance treatmentIgE-mediated food allergy in adult and pediatric patients aged ≥1 year age for the reduction of allergic reactions (Type I), including anaphylaxis, that may occur with accidental exposure to one or more foods. To be used in conjunction with food allergen avoidanceChronic spontaneous urticaria (CSU) in adults and adolescents ≥12 years of age who remain symptomatic despite H1 antihistamine treatmentLimitations of Use: Not indicated for: acute bronchospasm or status asthmaticus; emergency treatment of allergic reactions, including anaphylaxis; other forms of urticaria. IMPORTANT SAFETY INFORMATION WARNING: ANAPHYLAXISAnaphylaxis presenting as bronchospasm, hypotension, syncope, urticaria, and/or angioedema of the throat or tongue, has been reported to occur after administration of omalizumab products. Anaphylaxis has occurred as early as after the first dose of omalizumab products, but also has occurred beyond 1 year after beginning regularly administered treatment. Because of the risk of anaphylaxis, initiate OMLYCLO therapy in a healthcare setting and closely observe patients for an appropriate period of time after OMLYCLO administration.Health care providers administering OMLYCLO should be prepared to manage anaphylaxis which can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should symptoms occur. Selection of patients for self-administration of OMLYCLO should be based on criteria to mitigate risk from anaphylaxis. Contraindications: Severe hypersensitivity reaction to OMLYCLO or any ingredient of OMLYCLO. Anaphylaxis. Omalizumab products, including OMLYCLO, have been associated with anaphylaxis, reported in both clinical trials and postmarketing data. Patients with a history of anaphylaxis to foods, medications, or other causes face an increased risk. Initiate OMLYCLO only in a healthcare setting with anaphylaxis management capabilities. Patients should be monitored for an appropriate period post-administration, informed of symptoms, and instructed to seek immediate medical care if they occur. Malignancy. Malignancies have been observed in clinical studies, with various cancer types reported. The long-term risk, especially in high-risk groups, is unknown. Acute Asthma Symptoms and Deteriorating Disease. Omalizumab products have not been shown to alleviate asthma exacerbations acutely. Do not use OMLYCLO to treat acute bronchospasm or status asthmaticus. Corticosteroid Reduction. Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of OMLYCLO therapy for asthma or CRSwNP. Eosinophilic Conditions. Be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy, especially upon reduction of oral corticosteroids. Fever, Arthralgia, and Rash. Stop OMLYCLO if a patient develops this constellation of signs and symptoms, including arthritis/arthralgia, rash, fever, and lymphadenopathy. Parasitic (Helminth) Infection. Monitor patients at high risk of geohelminth infection while on OMLYCLO therapy. Laboratory Tests. Omalizumab increases serum total IgE due to drug:IgE complexes. Do not use serum total IgE levels within one year of discontinuation to reassess dosing regimen, as they may not reflect steady-state free IgE. Potential Medication Error Related to Emergency Treatment of Anaphylaxis. OMLYCLO should not be used for the emergency treatment of allergic reactions, including anaphylaxis. Instruct patients that OMLYCLO is for maintenance use to reduce allergic reactions, including anaphylaxis, while avoiding food allergens. Most Common Adverse ReactionsAsthma: In patients ≥12 years, reported in ≥1%: arthralgia, general pain, leg pain, fatigue, dizziness, fracture, arm pain, pruritus, dermatitis, and earache. In pediatric patients (6 to <12 years), reported in ≥3%: nasopharyngitis, headache, pyrexia, upper abdominal pain, streptococcal pharyngitis, otitis media, viral gastroenteritis, arthropod bites, and epistaxis.CRSwNP: In ≥3% of adults: headache, injection site reactions, arthralgia, upper abdominal pain, and dizziness.IgE-Mediated Food Allergy: In ≥3% of patients: injection site reactions and pyrexia.CSU: In ≥2% of patients: nausea, nasopharyngitis, sinusitis, upper respiratory tract infections (viral and non-viral), arthralgia, headache, and cough. For more information, see Full Prescribing Information. About CelltrionCelltrion is a leading biopharmaceutical company that specializes in researching, developing, manufacturing, marketing and sales of innovative therapeutics that improve people's lives worldwide.

Notice to Shareholders [Guideline for Implementing the Shareholder Return Plan that Prioritizes Enhancing Shareholder Value]

Recently, the uncertainty in both domestic and international political and economic conditions, along with the resumption of short-selling, has led to continued instability in the stock market. In response, Celltrion once again emphasizes its commitment to making company-wide efforts aimed at enhancing shareholder value and increasing corporate value. ■ Continuing to implement the shareholder return plan that prioritizes enhancing shareholder value. Celltrion will continue to overcome challenging internal and external conditions while steadfastly implementing the 'Value-Up Program’, a corporate value enhancement plan promised to our shareholders. Through this, we will proceed with a shareholder return plan that prioritizes the enhancement of shareholder value without wavering. We aim to achieve three key goals: ▲ an annual growth rate of over 30% through 2027 ▲ a return on equity (ROE) of over 7% by 2027 through expanded profitability ▲ an average shareholder return rate of 40%. Celltrion will continue its shareholder return initiatives through stock buybacks, cancellations, and cash dividends. Just three days after announcing the Value-Up Program, we decided to acquire approximately 50 billion KRW worth of treasury stock and swiftly completed the purchase. Today (April 2), we have decided to cancel all of the treasury stock we recently acquired. We will continue to cancel all additional treasury stock purchased moving forward. Celltrion will continue to enhance shareholder value. If the coporate value remains undervalued, we will actively implement additional shareholder-friendly measures — including share buybacks, cancellations, and increased dividends — to protect shareholder interests. Amidst domestic and global market uncertainties, Celltrion plans to actively pursue all available means to enhance shareholder value with continuous monitoring and proactive responds. We are committed to continuing making every effort to prioritize shareholder value. Thank you.

Notice to Shareholders [UPDATE - Company's Position and Response Strategy Regarding the U.S. Trump Administration's Tariff Policy(2)]

Recently, U.S. President Trump signed an executive order imposing reciprocal tariff on all countries, leading to inquiries from some shareholders regarding whether tariffs will be applied to pharmaceuticals. On January 30th, we informed shareholders of the company's response strategies under consideration via the notice [Response Strategy to the U.S. Trump Administration’s Tariff Policy on Pharmaceuticals]. Given our shareholders' concerns, we provide the following update on our review: 1. Outlook on the Trump Administration's Drug Tariff Policy  President Trump briefly mentioned imposing tariffs on foreign-produced pharmaceuticals, along with semiconductors and steel, during his inauguration speech last month. On February 13 (local time), he decided on reciprocal tariffs, which impose duties on foreign goods equivalent to the tariffs those countries apply to U.S. products. This has heightened market interest in the potential implementation of pharmaceutical tariffs.As previously mentioned, pharmaceutical tariffs that could lead to drug price increases are showing a policy direction that directly contradicts President Trump's earlier stance, which showed notable institutional efforts to lower drug prices. In addition, on the 12th of this month, Mike Johnson, the Speaker of the House of Representatives, said in an interview with Reuters that some items including pharmaceuticals could be excluded from the reciprocal tariffs, so whether drug tariffs will actually be implemented still requires careful observation.  2. Company’s Response Strategy and Preparedness  As explained in our initial notice last month, we have already established a response system for various scenarios regarding potential U.S. drug tariffs. This system can be summarized as follows: Short-Term Response: Minimizing Tariff Impact for 2025  We have already completed pre-emptive measures to minimize the impact of potential tariffs for 2025. As of the end of January, we have transferred approximately nine months' worth of inventory for our products scheduled for U.S. sale in 2025. This ensures minimal impact on this year's U.S. sales, regardless of whether drug tariffs are imposed.Production through Contract Manufacturing Organization (CMO) is a common practice in the pharmaceutical industry. We have been producing finished Drug Products (DP) through local CMOs even before the emergence of tariff risks. Through negotiations with these manufacturers, we have already secured additional production capacity. This completes our response to minimize the impact of potential drug tariffs for 2025. Mid- to Long-Term Response: Focus on Drug Substance Exports and Consideration of Local Production Facilities  We are already focusing on exporting Drug Substance (DS), which are subject to significantly lower tariffs than finished DPs in the event that tariffs are implemented. Additionally, we are in discussions with local CMOs with sufficient manufacturing capabilities to explore product production cooperation. These efforts will allow us to respond to changing circumstances by expanding local finished DP manufacturing beyond current levels if necessary, depending on pharmaceutical tariff trends.Therefore, we have already established strategies to minimize the impact of tariffs even beyond 2026. However, we have been reviewing in detail the acquisition of a pharmaceutical raw material production facility in the United States since last year, and we plan to finalize the investment decision within the first half of this year. This will allow us to promptly develop more fundamental and sustainable countermeasures against protectionist trade risks. We will respond swiftly and effectively to all situations to ensure that our shareholders do not have concerns regarding the direction of the Trump administration's tariff policies. We will continuously share updates on related progress, striving to maintain our shareholders' trust and support for the company.  Thank you.

Notice to Shareholders [Response Strategy to the U.S. Trump Administration’s Tariff Policy on Pharmaceuticals]

Dear Shareholders, In a recent speech shortly after his inauguration, U.S. President Donald Trump briefly mentioned that, along with semiconductors and steel, foreign-produced pharmaceuticals would also be subject to tariffs. Given that some of our shareholders have expressed concerns regarding this statement, we would like to provide a brief overview of our current response strategy.  1. Outlook on the Trump Administration's Drug Tariff Policy To date, President Trump has not presented specific policy proposals regarding drug tariffs, and the actual implementation is still uncertain, requiring further review and policy observation.Tariffs on drugs could lead to rising drug prices in the U.S., imposing significant burdens on consumers and the healthcare system. Therefore, it is unclear whether President Trump will actually enforce such measures.Notably, during his first term, President Trump consistently pushed for lower drug prices, and this tariff policy would directly contradict his previous stance on drug pricing.  2. Company’s Response Strategy and Preparedness Since the election of President Trump, we have closely analyzed various scenarios regarding the possibility of tariffs and have already in place a system capable of responding immediately, regardless of how the policy is implemented. Short-Term Response: Securing Sufficient Inventory in the U.S. We currently have sufficient inventory of our products in the U.S. to meet demand until at least the third quarter of 2025, without the need for additional imports.For products that are expected to be depleted sooner, we have the capability to produce finished pharmaceuticals (DP) from active pharmaceutical ingredients (API) already imported to the U.S. Mid-Term Response: Shift to a DS-centric Supply Strategy If tariffs are sustained in the long term, we plan to focus on exporting drug substances (DS), which are subject to lower tariffs, rather than finished drug products (DP) that face higher tariffs, and adjust our strategy to produce finished drug products at local manufacturing sites.We are already exploring cooperation with local companies that have sufficient manufacturing capacity to produce our products. Long-Term Response: Evaluating Establishment of Local Manufacturing Facilities in the U.S. We are considering the acquisition or establishment of local manufacturing facilities in the U.S. capable of producing both finished drug products and drug substances.This would help us create a stable supply chain that is less affected by political and social changes in the U.S., while also expanding our market share in the U.S.  3. Exchange Rate Environment and Positive Outlook for Exporting Companies As mentioned earlier, if the Trump administration imposes tariffs, it is likely to increase the prices of consumer goods and raw materials in the U.S., leading to inflation.If inflation worsens, there is a higher possibility that the U.S. Federal Reserve will continue its tight monetary policy, which could result in sustained high exchange rates.A high exchange rate environment can be beneficial for global export companies like us, enhancing our competitiveness in the U.S. market and improving profitability.  In conclusion, we will continue to monitor the Trump administration's tariff policy direction and are fully prepared to respond immediately if the policy is enacted. Moreover, in light of the changes in the global economic environment, we will leverage exchange rate fluctuations to maintain a stable profit structure and actively pursue long-term growth strategies. Additionally, we will strive to minimize supply and sales risks and maximize shareholder value through sustainable growth. We thank our shareholders for their continued trust and support, and we promise to share updates on our response efforts promptly and transparently. Thank you.

Notice to Shareholders Regarding Updates on Our Business Progress

Dear shareholders, Despite the ongoing domestic and international uncertainties, Celltrion's business operations are progressing smoothly. We would also like to reaffirm our unwavering commitment to implementing management practices that enhance shareholder value.The business initiatives presented to domestic and international shareholders and investors during the Hong Kong Investor Day are progressing smoothly. The planned share cancellation within the year was promptly executed, as confirmed by the "Decision on Share Cancellation" disclosure on December 4. The remaining initiatives discussed during the Investor Day will proceed without any setbacks, and we will do our utmost to fulfill our commitments to shareholders and investors. The impact of increased financial market volatility, which has recently raised concerns among our shareholders, is expected to be limited. Recent domestic uncertainties may lead to short-term volatility in the financial market. However, as more than 90% of Celltrion's revenue is generated overseas, primarily in USD or EUR, depreciation of the Korean won against the US dollar is expected to have little to no negative impact on our business. Amid external uncertainties, we remain steadfast in carrying out our duties and strengthening our core capabilities, striving to translate our efforts into tangible results.Additionally, we will keep you posted on any information that needs to be shared throughout this process. We would like to reaffirm that enhancing shareholder value remains our top priority. The executive leadership and all employees remain fully committed to repaying the trust our esteemed shareholders have placed in Celltrion. Lastly, we sincerely thank our shareholders for your unwavering interest and support for Celltrion.
